我正在尝试使用python模块python:3-8.alpine构建基于asyncpg的图像。
这是我的Dockerfile的一部分:
FROM python:3.8-alpine
RUN apk add gcc
RUN apk add python3-dev
RUN pip3 install asyncpg
我添加了
gcc和python3-dev，因为我认为我需要它们才能根据文档https://magicstack.github.io/asyncpg/current/installation.html来构建asyncpg(但我不确定，我认为我应该能够在不构建此模块的情况下进行安装)但是在构建图像时出现以下错误:
gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -DTHREAD_STACK_SIZE=0x100000 -fPIC -I/usr/local/include/python3.8 -c asyncpg/pgproto/pgproto.c -o build/temp.linux-x86_64-3.8/asyncpg/pgproto/pgproto.o -O2 -fsigned-char -Wall -Wsign-compare -Wconversion
In file included from asyncpg/pgproto/pgproto.c:29:
/usr/local/include/python3.8/Python.h:11:10: fatal error: limits.h: No such file or directory
11 | #include <limits.h>
| ^~~~~~~~~~
compilation terminated.
error: command 'gcc' failed with exit status 1
如何解决此错误并安装
asyncpg？谢谢
最佳答案
您必须安装构建工具，而不仅仅是gcc。您也可以删除RUN apk add python3-dev步骤。由于您使用的是python作为基本图像。
FROM python:3.8-alpine
RUN apk add --no-cache build-base
RUN pip3 install asyncpg
